Abstract
Description
Technical Field
[0001] This utility model belongs to the field of terraced field soil and water conservation technology, specifically referring to the diversion channel for soil and water conservation on terraced field ridges. Background Technology
[0002] Terraced fields are strip-shaped platforms built along contour lines on slopes, which can effectively improve land utilization. Field ridges are earthen embankments located below the surface of the field, used to separate the height differences between different plots of land. They can slow down the flow of water and prevent soil erosion. Because field ridges themselves have a slope, some of the soil on their surface will still be lost during irrigation due to the impact of the water flow. Therefore, diversion channels are built.
[0003] When irrigating the terraces on both sides, the existing diversion channels have a large slope, which leads to excessively fast water flow. When irrigating directly on the terraces, the excessively fast water flow will erode the soil surface. As the water level on the terraces increases, there is a risk of backflow if drainage is not smooth. Water mixed with soil entering the diversion channels will still cause soil erosion, especially during rainfall, when the increased water flow will further affect soil and water conservation. Utility Model Content
[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides a diversion channel for soil and water conservation on terraced field embankments. It effectively solves the problem that the existing diversion channels have a large slope, which leads to excessive water flow speed and still causes soil erosion. It also solves the problem that the diversion channels cannot drain properly when the water flow increases in a short period of time during rainfall.
[0005] The technical solution adopted by this utility model is as follows: The water and soil conservation diversion channel for terraced fields proposed by this utility model includes a water diversion channel set in a pit on the upper surface of the terraced field. The two ends of the water diversion channel are respectively provided with connecting flanges. The inner wall of the water diversion channel is evenly distributed with rotating shafts along the length direction, and the rotating shafts are rotatably connected to the water diversion channel. The end of the rotating shaft inside the water diversion channel is connected to a buffer mechanism, and the two sides of the buffer mechanism are provided with water flow control components. At the same time, the water flow control components are also connected to the rotating shaft. The side wall of the water diversion channel is evenly distributed with drainage channels along the length direction. The buffer mechanism includes a buffer block fixed on the rotating shaft. The buffer block has buffer guide plates evenly distributed in the transverse direction on the inclined surface near the top. The buffer block has a slot on the inclined surface opposite to the buffer guide plates, and a backflushing plate is inserted and pulled into the slot.
[0006] As an improvement to this solution, the bottom of the backflushing plate is in contact with the inclined surface of the buffer block, and the bottom of the backflushing plate is evenly distributed with filter holes, and a filter screen is provided at the connection between the water diversion channel and the drainage channel.
[0007] As an improvement to this solution, the water flow control component includes a swing arm and a translation push rod. The swing arm is fixed to one end of the rotating shaft that passes through the water diversion channel, and the translation push rod is rotatably connected to each set of swing arms and is arranged parallel to the water diversion channel.
[0008] As an improvement to this solution, a pin is fixed to the end of the translation push rod near the water diversion channel. A fixed rod is rotatably connected to the inner wall of the water diversion channel, and a fixed groove is provided on the fixed rod. The fixed rod is engaged with the pin through the fixed groove to fix the translation push rod.
[0009] As an improvement to this solution, the cross-section of the water diversion channel is U-shaped, and the cross-section of the buffer block is triangular with rounded corners at each corner.
[0010] As an improvement to this solution, the buffer guide plate is a Z-shaped thin plate that gradually slopes downward, and the drainage channel is a U-shaped channel that opens outward.
[0011] The beneficial effects of this utility model by adopting the above structure are as follows:
[0012] 1. Buffer mechanisms are evenly distributed along the length of the water diversion channel. The slope per unit length is changed by buffer blocks, and the buffer guide plates and backwash scrapers on their surfaces are used to reduce the water flow velocity. At the same time, the filter holes can filter out and retain the mud in the water flow. Regular cleaning can return the mud to the field, which improves the ability to prevent soil erosion.
[0013] 2. The drainage channels with gradually widening openings on both sides and the filter screen on them can further reduce the speed of water flow during irrigation, avoid washing away the soil on the platform, and drain water when the water level on the platform is too high during the rainy season, and reduce the loss of soil on the platform by using the filter screen during drainage.
[0014] 3. Equipped with a water flow control component, the rotating shaft and its buffer block can be rotated by a swing arm and a translation push rod, which increases the gap between the buffer block and the water diversion channel, accelerates the discharge of water in the water diversion channel, and avoids the problem of soil and water loss caused by water accumulation on both sides of the platform exceeding the height of the field ridge due to poor drainage.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the water and soil conservation diversion channel for terraced fields proposed in this utility model includes a water diversion channel 2 located in a pit on the upper surface of the terrace 1. The cross-section of the water diversion channel 2 is U-shaped. Connecting flanges 3 are provided at both ends of the water diversion channel 2. Rotating shafts 5 are evenly distributed along the length direction on the inner wall of the water diversion channel 2, and the rotating shafts 5 are rotatably connected to the water diversion channel 2. A buffer mechanism 4 is connected to the end of the rotating shaft 5 inside the water diversion channel 2, and water flow control components 6 are provided on both sides of the buffer mechanism 4. At the same time, the water flow control components 6 are also connected to the rotating shaft 5. Drainage channels 7 are evenly distributed along the length direction on the side wall of the water diversion channel 2. The drainage channels 7 are U-shaped channels that open outwards.
[0023] The buffer mechanism 4 can effectively reduce the fringe of the water flow, and the water flow control component 6 can regulate the drainage volume in the water diversion channel 2, avoiding overflow caused by a surge in water volume in a short period of time during the rainy season.
[0024] like Figure 1 and Figure 3As shown, the buffer mechanism 4 includes a buffer block 8 fixed on the rotating shaft 5. Buffer guide plates 9 are evenly distributed horizontally on the inclined surface near the top of the buffer block 8. The buffer guide plates 9 are Z-shaped thin plates that gradually slope downwards. A slot 10 is provided on the inclined surface of the buffer block 8 opposite to the buffer guide plates 9. The cross-section of the buffer block 8 is triangular and all corners are rounded. A backflush plate 11 is inserted and pulled into the slot 10. The bottom of the backflush plate 11 is in contact with the inclined surface of the buffer block 8, and filter holes 12 are evenly distributed on the bottom of the backflush plate 11. A filter screen 13 is provided at the connection between the water diversion channel 2 and the drainage channel 7.
[0025] The buffer block 8, buffer guide plate 9 and backwash plate 11 can reduce the speed of the water flow through the layers to ensure that the flow velocity is not too high due to the slope. The filter holes 12 and filter screen 13 can also trap the mud in the water to prevent it from being lost.
[0026] like Figure 1 and Figure 2 As shown, in order to regulate the drainage volume in the water diversion channel 2 and prevent overflow, the water flow regulation component 6 includes a swing rod 14 and a translation push rod 15. The swing rod 14 is fixed to one end of the rotating shaft 5 that passes through the water diversion channel 2, and the translation push rod 15 is rotatably connected to each set of swing rods 14 and is arranged parallel to the water diversion channel 2.
[0027] like Figure 2 As shown, a pin 16 is fixed to the end of the translation push rod 15 near the water diversion channel 2. A fixing rod 17 is rotatably connected to the inner wall of the water diversion channel 2, and a fixing groove 18 is provided on the fixing rod 17. The fixing rod 17 is engaged with the pin 16 through the fixing groove 18 to fix the translation push rod 15.
[0028] The translation push rod 15 enables synchronous driving of multiple sets of swing rods 14, saving operation time, and can be fixed by the pin 16 and the fixing rod 17.
[0029] In practical use, a groove for laying is dug in advance on the terrace 1, then the water diversion channel 2 is buried and the sides are piled up with soil. The channel is then installed and spliced sequentially through the connecting flanges 3 at both ends of the water diversion channel 2. When diverting water, the water flows in from the upper side of the water diversion channel 2 and flows down the slope of the water diversion channel 2. When it passes the buffer block 8, the slope of the buffer block 8 is used to lift the water flow and intercept it until the water flow exceeds the highest point of the buffer block 8 and then flows down. During this process, the flow velocity of the water is further reduced by the surface contour of the buffer guide plate 9. After the water flow passes the highest point of the buffer block 8, it falls along the backwash plate 11 and is decelerated by the arc at the bottom of the backwash plate 11. At the same time, the sediment is removed. After being filtered through the filter holes 12, the backwash plate 11 can be removed and emptied periodically. During irrigation, the water in the water diversion channel 2 is discharged to both sides through the drainage channel 7. When it rains and the water level on the platform is too high, the water is filtered through the filter screen 13 and then discharged into the water diversion channel 2. At the same time, the fixing rod 17 is separated from the pin 16, and the translation push rod 15 is rotated to drive the swing rod 14 to rotate, so that the bottom of the buffer block 8 tends to be parallel to the bottom of the water diversion channel 2. Then, the pin 16 is clamped and fixed by the fixing groove 18 on the fixing rod 17, so that the water can flow smoothly between the buffer block 8 and the water diversion channel 2, improving the smoothness of discharge and avoiding water accumulation. The above is the entire process of using the water and soil conservation diversion channel of the terrace 1.
[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
